EMI Receiver Instructions for Use
These places leak out. The solution is: all the gaps must be blocked with conductive voltage strips, and the window
Different light-transmitting shielding materials should be used for the mouth. All input/output lines must pass through filters and shielded enclosures
external circuit connections. If the selection or installation of conductive voltage strips and filters is not suitable, or the light-transmitting screen of the window
If the performance of the shielding material is not good, there will be electromagnetic leakage, and the near-field diagnostic probe can be used to check the leakage location and leakage.
the size of.
Measurement methods
1. Device connection
Connect the near-field probe to the spectrum input of the spectrum analyzer.
2. Parameter setting
1) Reset the instrument
—Press [Preset]
2) Setting parameters
—Press[FREQ]key to adjust the center frequency to the estimated detection frequency
—Press[SPAN]key to set the sweep width to the widest first, so that the display will be a panoramic spectrum.
Move the probe (as shown in the figure) at the place where the EUT needs to be inspected (such as gaps, ventilation windows, etc.).
Adjust the center frequency to a relatively large spectral line, and use the frequency marker to observe the frequency and amplitude of the spectral line.
